Yes.

Yes. That's what breakpoints are for. If you set a breakpoint on
panic, you'll go into the debugger. But you don't need that, since
you go into the debugger on panic anyway.
If you're expecting a breakpoint or panic, and you want to do it in
gdb as opposed to ddb, set gdb mode ahead of time. This is also
useful for debugging ddb :-)
